1 Introduction
1.1 The declared service
The domestic transmission capacity service (DTCS) is a generic service that can be
used for the carriage of voice, data or other communications using wideband or
broadband carriage (the minimum data rate in the current declaration is
2.048 Megabits per second (Mbit/s)). Carriers and/or carriage service providers
(CSPs) can use transmission capacity to set up their own networks for aggregated
voice or data channels, or for integrated data traffic (such as voice, video and data).
In respect of the declared service, the Australian Competition and Consumer
Commission (the Commission) recognises a number of types of transmission capacity
services, including:
� inter-capital transmission
� ‘other’ transmission (e.g. capital-regional routes)
� inter-exchange local transmission, and
� tail-end transmission.1
1.2 Background to the DTCS declaration
The supply of various types of transmission capacity was deemed to be a declared
service in June 1997.2 The declaration was subsequently varied in 1998, 2001 and
2004. In 2004, the Commission put in place a new service description which, in
addition to inter-capital transmission,3 excluded 14 nominated capital-regional routes
from the declaration.4
In March 2009 the Commission varied the 2004 DTCS declaration to reflect the
Commission’s final decision on Telstra’s transmission exemption applications (Final
Exemption Decision).5 The Final Exemption Decision exempted capital-regional
transmission on an additional 9 capital regional routes and inter-exchange
transmission in 16 capital city areas and 72 metropolitan areas.

The current declaration took effect on 1 April 2009 and is due to expire on
31 March 2014. The service description is set out in full at Appendix 1.
1.3 Review of the DTCS declaration
The Commission commenced a public inquiry in November 2009 to review the
existing DTCS declaration (and if necessary vary the declaration) pursuant to
sections 152AO and 152AL of the Trade Practices Act 1974 (the Act), subsection
33(3) of the Acts Interpretation Act (AIA) and Part 25 of the Telecommunications Act
1997 (Telecommunications Act).
The purpose of the review was to clarify the DTCS service description and assess
whether the current DTCS service description covers all commonly used network
interfaces on transmission networks in Australia such as the PDH (Plesiochronous
Digital Hierarchy), SDH (Synchronous Digital Hierarchy) and Ethernet network
interfaces.
The Commission released the Domestic Transmission Capacity Service – an ACCC
Discussion Paper reviewing the declaration of the domestic transmission capacity
service (Discussion paper) in November 2009 in order to inform the declaration
review. The Commission received submissions and briefings in response to the
Discussion paper between January and April 2010 from:
� AAPT Ltd (AAPT)
� Herbert Geer on behalf of Chime Communications Pty Ltd, Primus
Telecommunications Pty Ltd, Agile Pty Ltd and Wideband Networks Pty Ltd
(the Access seekers)
� Macquarie Telecom Pty Limited (Macquarie Telecom)
� Singtel Optus Pty Limited (Optus)
� Telstra Corporation Ltd (Telstra), and
� Vodafone Hutchison Australia Limited (VHA).
AAPT, VHA, Macquarie Telecom, Telstra, Gilbert and Tobin and Optus
representatives also attended a roundtable meeting with Commission staff on
10 March 2010.
On 20 July 2010 the Commission released the Domestic Transmission Capacity
Service – an ACCC Draft Final Report on reviewing the declaration of the domestic
transmission capacity service (Draft final report). In response to the Draft final report
the Commission received submissions in July and August 2010 from:
� Austar Entertainment Pty Limited (Austar)
� Macquarie Telecom
� Optus
3
� Telstra, and
� VHA.
All submissions have been considered and reflected where appropriate in this Final
report on the DTCS declaration review.
The public submissions and briefings that were lodged are also available on the
Commission’s website at www.accc.gov.au. A list can also be found in Appendix 4 of
this Final report. Further information on the Commission’s approach to declaration
inquiries is outlined in its publication Telecommunications services – Declaration
provisions – a guide to the declaration provisions of Part XIC of the Trade Practices
Act, July 1999, available on the Commission’s website at www.accc.gov.au.
1.4 Summary of findings of the inquiry
The Commission’s view is that the DTCS declaration should be varied so that it
covers all commonly used network interfaces used on transmission networks in
Australia. The Commission notes that the intention behind the DTCS service
description is that it be technologically neutral, not restricted to any particular
network interface and apply to the underlying transmission service regardless of the
type of interface used.6 In order to achieve this, the Commission has specifically
added Ethernet network interfaces to the other commonly used network interfaces
referred to in the service description.
The Commission notes that the standard access obligations only apply to a carrier or
carriage service provider that supplies declared services, whether to itself or to others
(ie. ‘active declared services’ under subsection 152AR(2) of the Act). The
Commission considers that access providers need only provide access to the DTCS
via a network interface and data rate which the access provider uses to provide the
service to itself or others within a particular exchange service area (ESA). The
Commission is of the view that it is in the long term interests of end-users (LTIE) for
access seekers to have the right to request access via a particular network interface
and data rate where there is more than one type being used by the access provider in
the deployment of the DTCS at an ESA.
The Commission finds that the revised DTCS service description (set out in
Appendix 2) is in LTIE. The Commission has reached this view for the following
reasons:
� Promotion of competition – the Commission considers that varying the
service description will promote competition by ensuring that access seekers
continue to be provided with the DTCS without being limited by the network
interface used to deliver the service. Varying the service description will also

Telecommunications (Transitional Provisions and Consequential Amendments) Act 1997, June 1997,
p.63.

promote competition in downstream services as transmission services
delivered via Ethernet network interfaces create opportunities for retail
operators to offer competitive services to end-users.
� Any-to-any connectivity – the Commission considers that any-to-any
connectivity will be promoted by the variation to the declaration as it remains
technologically neutral in terms of network interfaces through which any-to-
any connectivity may be achieved. Any-to-any connectivity will also be
promoted for voice and data services which use transmission services
delivered via Ethernet network interfaces.
� Economically efficient use of and investment in infrastructure – the
Commission considers that efficient use of infrastructure used to provide the
DTCS will be promoted by the proposed variation. The Ethernet network
interface is common in modern network equipment and likely to be used in
future upgrades to Australian telecommunication networks. The Commission
notes that adapters or other equipment are unlikely to be necessary where
Ethernet network interfaces are used given the prevalence of Ethernet in the
market. The Commission considers that the use of Ethernet network interfaces
is likely therefore to be more cost effective than other network interfaces. The
Commission is also of the view that the variation to the declaration will
provide certainty for CSPs in their investment decisions and help them build a
customer base as a consequence. The Commission considers that this will
encourage them to invest in efficient infrastructure once their retail customer
base reaches a certain threshold.

2 Issues raised in the review process
The Commission conducted a public inquiry to clarify whether the DTCS service
description covers all commonly used network interfaces on transmission networks in
Australia such as the PDH, SDH and Ethernet network interfaces.
The current opening description of the DTCS (detailed in Appendix 1) describes the
DTCS as:
…a service for the carriage of certain communications from one transmission
point to another transmission point via network interfaces at a designated rate
on a permanent basis by means of guided and/or unguided electromagnetic
energy, except communications between [certain transmission points]…
The designated rate is defined as:
…a transmission rate of 2.048 Megabits per second, 4.096 Megabits per
second, 6.144 Megabits per second, 8.192 Megabits per second, 34 to 357
Megabits per second, 140/155 Megabits per second (or higher orders).8
The data rates included in the above definition of a ‘designated rate’ of the DTCS
service description relate to network interfaces known in the industry as PDH and
SDH.
Commonly used PDH data rates include:
� 2.048 Mbit/s per second – also referred to as E1
� 34.368 Mbit/s – also referred to as E3
� 139.264 Mbit/s – also referred to as E4, and
� 44.736 Mbit/s – used for digital TV signals.
Commonly used SDH data rates include:
� 155.520 Mbit/s – also referred to as STM 1
� 622.080 Mbit/s – also referred to as STM 4
� 2488.320 Mbit/s – also referred to as STM 16, and
� 9953.280 Mbit/s – also referred to as STM 64.
7 The reference here to 35 is a typographical error and should be 45 (refer to the service description in
the 2004 DTCS Declaration review). Herbert Geer, Submissions from Chime Communications Pty
Ltd, Primus Telecommunications Pty Ltd, Agile Pty Ltd and Wideband Networks Pty Ltd (the Access
Seekers) in response to the ACCC’s discussion paper reviewing the declaration for the Domestic
Transmission Capacity Service (DTCS), 1 February 2010 (Access seeker submission on discussion
paper), p.4; Telstra submission on Draft final report, p.16. 8 ACCC, 2009 DTCS Final report, p.41.
6
The current DTCS service description may be ambiguous on its face as to whether it
includes the following Ethernet data rates:
� 10 Mbit/s – also referred to as Ethernet
� 100 Mbit/s – also referred to as Fast Ethernet
� 1000 Mbit/s – also referred to as Gigabit Ethernet
� 10000 Mbit/s – also referred to as 10 Gigabit Ethernet
In the Discussion paper, the Commission proposed to vary the DTCS declaration by
including the following definitions:
a designated rate is a transmission rate of 2.048 Megabits per second or
higher using Ethernet, PDH or SDH interface protocols.
Ethernet, PDH or SDH interface protocols are Ethernet, Plesiochronous
Digital Hierarchy (PDH) or Synchronous Digital Hierarchy (SDH) interface
protocols as established and amended from time to time by the International
Telecommunications Union, Telecommunication Standardization Sector
(ITU-T) or the Institute of Electrical and Electronic Engineers (IEEE). 9
The Draft final report proposed the following changes to the current opening
description of the DTCS:
� replacing of the current definition of ‘designated rate’ with a new definition of
‘network interfaces’
� describing network interfaces as ‘symmetric’, and
� describing the basis upon which transmission is delivered as ‘uncontended’.
The opening description of the DTCS proposed in the Draft final report is as follows:
…a service for the carriage of certain communications from one transmission
point to another transmission point via symmetric network interfaces on a
permanent uncontended basis by means of guided and/or unguided
electromagnetic energy…
The Commission defines ‘uncontended’ as dedicated and not shared and ‘network
interfaces’ non-exhaustively to:
include Ethernet, Plesiochronous Digital Hierarchy (PDH) and Synchronous
Digital Hierarchy (SDH) interface protocols used to provide a transmission rate
of 2.048 Megabits per second or above which an access provider provides to
itself or others10
The revised service description proposed by the Commission in the Draft final
report is set out in full in Appendix 2 of this Final report.

Submissions against variation
Telstra submits that it is not necessary or appropriate to vary the service description to
include Ethernet network interfaces for a number of reasons.
First, the DTCS in its current form already enables access seekers to convert an
underlying (declared) SDH service (acquired from Telstra or another provider) to
‘Ethernet over SDH’. Telstra argues that:
� there is no material difference between the cost for access seekers to convert
SDH transmission services to Ethernet and the cost of Telstra to supply
Ethernet over SDH at the wholesale level
� the costs of multiplexing and other electronic equipment have not been
considered a barrier to entry because they are relatively low, are declining
over time and may be recovered
� there is no efficiency gain from extending regulation to Ethernet services
� in some circumstances the supply of carrier grade Ethernet can be created
more cheaply from underlying DTCS by access seekers than by Telstra
supplying the same services (for example, the supply of a 155 Mbit/s STM-1
SDH service)
� Ethernet conversion by the access seeker provides a wider footprint than
Telstra’s own Ethernet over SDH. For Telstra to provide ‘Ethernet over SDH’
an Ethernet interface card must be inserted into a pre-existing Next
Generation Add Drop Multiplexer (NG-ADM). However, not all ADMs have
been upgraded to the Next Generation Network. Telstra does not offer
‘Ethernet over SDH’ in all geographic locations where SDH is available as it
is not economical for it to do so unless access seekers have a significant block
of capacity, and
� it is simpler for access seekers to self-supply ‘Ethernet over SDH’ as they only
need to acquire a standard SDH transmission service from Telstra at a
specified bandwidth and install a Network Terminating Unit (NTU) at the end
of each SDH transmission link. Similarly, access seekers can provide Ethernet
via the declared ULLS service through ‘Ethernet over Copper’. The
equipment required to ‘self-supply’ is also readily available and allows access
seekers to control their traffic across their networks.11
Secondly, Telstra submits that there is sufficient evidence of effective competition
and no evidence of market failure in Ethernet markets. Telstra reasons that:

� there is no undeclared network bottleneck in Ethernet markets, or any
evidence of enduring or unregulated bottlenecks
� there are many competitors offering Ethernet services demonstrating low
barriers to entry
� wholesale Ethernet services are widely supplied on a commercially
competitive and unregulated basis
� competition is already effective in downstream markets
� ‘Ethernet over fibre’ normally coincides with routes where infrastructure-
based competition already exists. Carriers and carriage service providers
which do not own their own fibre can buy the regulated SDH transmission
service provided by Telstra to create their own Ethernet services. In both
cases, Telstra argues that there is already significant product differentiation in
these markets
� exempted regions under-represent the true scale of competition and that many
more areas where Ethernet is available should be made exempt due to high
levels of competition, and
� pricing of Telstra’s wholesale ‘Ethernet over SDH’ is effectively constrained
because access seekers can convert SDH services themselves and self-supply
Ethernet over copper via the declared ULLS service.12
Thirdly, Telstra argues that it is unnecessary to vary the current DTCS service
description because it would have adverse consequences if implemented. Specifically,
the removal of the stipulated designated speeds would allow access seekers to seek
DTCS and Ethernet at a range of non-standard bandwidths in a way that is
inconsistent with the rates contemplated by international standards.13
Finally, Telstra argues that the variation is unnecessary because it is premature,
potentially harmful and has adverse ramifications for the future supply of the DTCS
and all types of Ethernet. Telstra considers there is insufficient evidence to support
the conclusion that regulation of Ethernet is in the LTIE and that further market
analysis is necessary. Telstra also considers that there is no evidence of an
unregulated enduring bottleneck whilst describing the ‘Ethernet over fibre’ service as
evolving and in the earlier stages of its product life cycle. Telstra submits that it
should not be regulated (if at all) until the markets have matured and to do otherwise
would adversely influence technology choice and impede its adoption.14
AAPT agrees with Telstra that the DTCS declaration should not be varied. AAPT is
not aware of any enduring bottleneck issue in the wholesale or retail Ethernet markets
and raises concerns over regulation without any reference to quality of service or
security aspects of the services. AAPT considers that the current DTCS service

description is unclear as to whether it includes Ethernet services. AAPT is of the view
that it does not cover commonly used Ethernet data rates of 10 Mbit/s and 100 Mbit/s,
but might catch Ethernet data rates such as GE or 10GE.15
Telstra and AAPT agree on the importance of Ethernet network interfaces in the
delivery of telecommunication services. Telstra describes Ethernet as:
� widely supplied on a commercially competitive and unregulated basis
� a common ‘interface protocol’ with a wide range of services and devices
interconnecting, and
� used in a multitude of services and which have, in effect, become ubiquitous.16
Submissions supporting variation because Ethernet network interfaces are used
in transmission services
Optus, Macquarie Telecom, VHA, Austar and Access seeker submission agree that
Ethernet network interfaces are widely used in transmission capacity services and
should be included in the DTCS service description.17
Submitters describe Ethernet
network interfaces in the following ways:
� a key standard in the market with the Australian Communications and Media
Authority (ACMA) recognising a link between the growing demand for higher
bandwidth and increasing market presence of Ethernet network interfaces18
� the preferred network interface of the developing broadband network
environment19
� the preferred interface for providing cost effective and scalable interfaces.
Macquarie Telecom notes that it, and many other carriers, are replacing many
of the SDH interfaces used in their core networks with Ethernet interfaces20

� the network interface with the potential (for carriage of internet protocol
services) of allowing use of cheaper equipment than that required by PDH and
SDH standards further facilitating competition in downstream markets21
� the default standard for telecommunications equipment vendors22
� a network interface which is rapidly replacing earlier standards.23
Access
seekers consider Ethernet layer services (as opposed to internet protocol (IP))
as essential for connecting IP DSLAMs back to core networks24
� a network interface which is consistent with the future technology path for
mobile and fixed services25
and the inclusion of which supports the principle
that regulation should be technology neutral.26
The Access seeker submission argues that if it is accepted that the DTCS service
description should be ‘generic’ and ‘technologically neutral’ then it must follow that
the service description should apply to all transmission network interfaces commonly
used over the Australian network. To do otherwise would risk divorcing the DTCS
from the guiding principle of contestability applied by the Commission.27
The Access seeker submission also notes that if the only transmission service that
Telstra offers in a non-contested transmission route is an Ethernet based service or
other service not at the ‘designated rate’, they will have no recourse to a regulated
service in respect of that transmission route even though that route is not contested.
Access seekers submit that this is not in the LTIE.28
Similarly Macquarie Telecom and Optus note that Telstra has refused to supply
wholesale transmission services using Ethernet network interfaces in the past,
particularly in non-CBD areas, and that a technology-neutral service description is
likely to change Telstra’s policy on the supply of transmission services and thereby
enable them to offer competitive services to end-users.29
Telstra however denies that
it has refused to supply Ethernet services in areas enabled for the provision of such
services.30
Submissions supporting variation because the service description is unclear
Optus, Macquarie Telecom, VHA and the Access seekers agree that the revised
service description will clarify the scope of the existing DTCS service description and

should be varied to specifically refer to Ethernet network interfaces as well as PDH
and SDH.31
Macquarie Telecom submits that Ethernet network interfaces are not included in the
current DTCS service description as the ‘designated rate’ is defined by data rates
which do not match those of Ethernet network interfaces. Macquarie Telecom
suggests that, at best, Ethernet network interfaces could be considered as partly
included in the service description as data rates of one Gigabit (1000 Mbit/s per
second) or more arguably fall within the scope of the definition of the designated rate
while data rates of 10 Mbit/s or 100 Mbit/s do not.32
Optus notes that it could be
argued that Ethernet network interfaces are included by implication as the service
description refers to “higher orders” of bandwidth or excluded on the basis that the
lower orders of bandwidth listed specifically refer to PDH and SDH protocols.33
The Commission’s view
The Commission notes that all submissions are in agreement over the importance of
Ethernet network interfaces in the delivery of transmission services. The Commission
considers that the role and importance of Ethernet network interfaces is therefore well
established and accepted by industry.
The Commission notes that most submissions also agree that there exists a level of
ambiguity surrounding the particular network interfaces which are covered by the
DTCS service description. The Commission considers that variation of the DTCS is
necessary in order to remove this ambiguity and to ensure that the service description
covers all commonly used network interfaces in the Australian network. Maintaining
the DTCS service description in its current form would fail to address the ambiguity
over the network interface which may be used to supply the DTCS and risks
excluding from regulation transmission services which use Ethernet network
interfaces in markets which lack competition.

3 Proposed variations to the DTCS service description in
submissions
3.1 Discussion paper
The Commission received submissions which identified further changes or areas
requiring clarification to the form of the proposed service description in the
Discussion paper. Parties submitted that the DTCS service description needed to:
� clarify the calculation of the bandwidth, particularly with regard to Ethernet
services
� clarify issues over Ethernet’s application in the Open Systems Interconnection
(OSI) model
� include an ‘automatic exemptions clause’ that adjusts the level of regulation to
match the level of competition
� define network interfaces based on international standards, such as the
International Telecommunications Union, Telecommunication Standardization
Sector (ITU-T) or the Institute of Electrical and Electronic Engineers (IEEE).
Clarify the calculation of the bandwidth
Telstra sought the clarification of bandwidth, particularly with regard to Ethernet
services and whether it included the entire frame or just the payload within the
Ethernet frame.
Telstra raised the possibility of access seekers requesting transmission services at
speeds outside current bandwidth increments and in a manner inconsistent with
international standards.34
Telstra referred to the approach in the United Kingdom
(UK), which limits regulation of Ethernet to low bandwidth (i.e. less than 1 Gbp/s)
transmission services35
and suggested the following draft wording:
a designated rate is a transmission rate of:
(a) 2.048 Megabits per second, 4.096 Megabits per second, 6.144 Megabits per
second, 8.192 Megabits per second, 34 to 35 Megabits per second, 140/155
Megabits per second (or higher orders) using SDH or PDH presentation; or
(b) a transmission rate of 10, 100 or 1000 Megabits per second using ‘Ethernet
over SDH’ delivery where neither transmission point is a customer
transmission point
34
Telstra submission on discussion paper, pp.4 (in Executive Summary), 15, 33. 35
Telstra submission on discussion paper, pp.27, 32.
13
Telstra submitted that the words ‘where neither transmission point is a customer
transmission point’ ensures that the service description applies to inter-exchange
services only.36
Clarify concerns over Ethernet’s application in the Open Systems
Interconnection (OSI) model
Optus submitted that it would be inappropriate for the declaration to be expanded to
cover valued-added services at higher levels such as point to multipoint and VPLS
and that it should refer to point to point services delivered over a Layer 2 Ethernet
interface if the Commission does not want to broaden the scope of the service
description. Optus proposed the following draft:
For the avoidance of doubt, an Ethernet interface protocol in this context
applies only to point to point services provided over a layer 2 Ethernet interface
(where “Layer 2” refers to the Open System Interconnection Reference
Model).37
Telstra submitted that the proposed variation in the Discussion paper was too broad in
scope and application and would result in regulation of the same underlying
infrastructure at multiple levels of carriage technologies. Telstra claimed the proposed
variation may:
� regulate SDH transmission and Ethernet services conveyed via SDH
transmission. Should the Commission decide that Ethernet is to be regulated,
then any variation to the existing DTCS service description should be
expressly confined to ‘Ethernet over SDH’ in non-metropolitan areas that are
not yet subject to effective competition. Telstra proposed that the Commission
limit the scope of its variation as described in the previous point above.
� regulate Ethernet services supplied over the local access infrastructure
(including ULLS and FTTP networks) thereby regulating wholesale DSL,
Business Grade Ethernet and Ethernet Private Network Services. It could also
cover other Layer 2 and Layer 3 ‘routed’ services and apply across multiple
infrastructure types, including fibre, the CAN and microwave.38
Telstra also submitted that if the service description includes Ethernet services it
should state that it is supplied over mainly ‘Layer 1’ and ‘Layer 2’ transport
technologies. Also, if the service description is not confined to ‘Ethernet over SDH’,
any variation should make clear that the declaration applies to wholesale carrier grade
services in Telstra’s network and not to the business grade services (i.e. ‘Ethernet
over fibre’). Telstra proposed the following draft:

Ethernet Briefing), p.2.
14
The domestic transmission capacity service is a service for the carriage of certain
communications from one transmission point to another transmission point via
network interfaces at a designated rate on a permanent, uncontended, circuit
switched basis by means of guided and/or unguided electromagnetic energy…
Telstra submitted that the words ‘circuit switched’ would ensure that services covered
by the DTCS service description remain as a ‘Layer 2’ service (without routing) and
do not include ‘Layer 3’ services (with routing).39
Telstra also submitted that the proposed variation in the Discussion paper may have
the unintended effect of:
� regulating other transport protocols, such as ATM, which are not regulated in
the core network as part of the DTCS service but will be regulated if used to
supply Ethernet
� applying to basic residential broadband services provided over the
unconditioned local loop such as ADSL. In this manner, wholesale customers
of Telstra that are acquiring ULLS and then selling ADSL may become
subject to regulation, potentially requiring the wholesaling of their retail
ADSL services on price and non-price terms potentially determined by the
ACCC.
� applying to a wide range of new wholesale and retail markets and services
including those currently being developed by NBN Co. Telstra argues that
such regulation may delay the development and roll-out of next generation
Ethernet-based access services, thus hampering innovation and efficiency.40
In Telstra’s opinion, any regulation of emerging national broadband network (NBN)
services would be premature in circumstances where the future industry structure is
still the subject of ongoing analysis and negotiation, and specifically that ‘Ethernet
over fibre’ should not be subject to regulation until its use has fully matured.
Nonetheless, Telstra submitted that if the proposed variation is implemented and
Ethernet is regulated, that regulation should not apply to any transmission routes
where NBN Co has overbuilt existing transmission of any carrier. 41
The Access seeker submission stated that due to the nature of transmission services it
was not possible to regulate a transmission service on a ‘generic’ basis without
creating, at least in theory, the possibility of ‘double regulation’. Access seekers
submitted that double regulation is possible with PDH and SDH network interfaces
when, for example, an access seeker obtains a service from Telstra using STM 1 and
that access seeker supplies its spare capacity on a wholesale basis to other access
seekers at a lower ‘designated rate’.42

Include an ‘automatic exemptions’ clause
Telstra noted the removal of access providers’ ability to seek ordinary exemptions
under the proposed Telecommunications Legislation Amendment (Competition and
Consumer Safeguards) Bill (the CACS Bill) or the Telecommunications Legislation
Amendment (National Broadband Network Measures—Access Arrangements) Bill
2010 (Access Bill) (the proposed legislation).43
As a consequence Telstra requested
that the Commission adopt a new methodology for declarations, involving an in-built
mechanism that adjusts the level of regulation to match the level of competition.44
The determination of whether a particular route is competitive would be based on
data taken from record keeping rules (RKRs).45
Telstra submitted that if the Commission were to implement a variation to the DTCS
service description it should also take the opportunity to vary the service description
to ensure that declaration does not apply to:
� any transmission routes where NBN Co has overbuilt existing transmission of
any carriers
� any transmission routes where excess capacity exists and there is more than
one infrastructure-based competitor, and
� where there are more than two infrastructure-based competitors on a route.46
Telstra submitted that a similar mechanism has been adopted by the Australian
Competition Tribunal in Application by Chime (no 3) [2009] ACompT 4.47
Define network interfaces based on international standards, such as the ITU-T
and IEEE 48
VHA submitted that the Commission should refer to particular ITU-T or IEEE
standards.49
Optus and VHA requested that new protocols and interface standards be
added to the service description as they are recognised by the ITU-T and IEEE.
VHA suggested that the Commission determine that including additional network
interfaces is a variation of a minor nature for the purpose of s. 152AO(3) of the Act
and expressly stated that, notwithstanding the reference to particular network
interfaces, the service description is intended to be technology neutral. Alternatively,
the definition of the expression ‘designated rate’ could be drafted non-exhaustively to

include SDH, PDH, Ethernet or any other protocol which provides similar
functionality. 50
The Commission’s view
The Commission is of the view that the DTCS declaration should apply to all
transmission services regardless of the network interface used to provide the service.
However, the Commission has carefully considered all submissions and recognises
that there is a level of ambiguity about the network interfaces covered by the DTCS
service description in its current form.
The Commission considers that this ambiguity can be addressed by amending the
service description to simplify the opening description of the DTCS and include a
new definition of network interfaces that more closely reflects industry practice and is
sufficiently technological neutral to be able to adapt to changes in technology.
In response to these submissions on the Discussion paper, the Commission revised
the opening description of the DTCS in the Draft final report:
The domestic transmission capacity service is a service for the carriage of
certain communications from one transmission point to another
transmission point via symmetric network interfaces on a permanent
uncontended basis by means of guided and/or unguided electromagnetic
energy, except communications between....
The revision clarifies that transmission services are provided on a symmetric and
permanent basis to a particular access seeker and are not shared with other access
seekers.
The new definition of ‘network interfaces’ replaces the current definition of
‘designated rate’ and expressly, but not exhaustively, identifies the widely used
transmission network interfaces PDH, SDH and Ethernet. This would provide
certainty as to the network interfaces covered by the service description and provide
sufficient flexibility to accommodate any changes in industry practice about the
network interfaces used for transmission services.
The new definition of ‘network interfaces’ also specifies a minimum transmission
rate of 2.048 Mbit/s or above which access providers provide to themselves or others.
This would address concerns about access to transmission rates that are not
commonly available by capturing only the transmission services above a certain
speed that the access provider already provides itself (or others).
In addition, a new definition of ‘uncontended’ is introduced to clarify that
transmission services are dedicated to particular access seekers and are not shared
50
Optus submission on discussion paper, p. 8. VHA submission on discussion paper, p. 5.
17
with other access seekers. The Commission has also corrected minor grammatical
errors in the service description.
The revised service description is set out in full in Appendix 2.
The Commission has not included an automatic exclusion clause (as proposed by
Telstra) in the context of this review because it considers that it would go beyond the
bounds of the purpose of this inquiry and may be inconsistent with proposed
legislation.51
The Act does not expressly provide for conditions to be placed on
declarations; rather, exemptions are available to ‘wind back’ the application of
standard access obligations in certain circumstances after a public inquiry. With
respect to the Australian Competition Tribunal’s adoption of such a mechanism, the
Commission notes that the Tribunal adopted this mechanism in the exemptions
context, where the Act expressly provides for conditions and limitations to be placed
on exemptions. The Commission is of view that it would not be appropriate to adopt
such a mechanism in the context of this inquiry. In relation to the proposed
legislation, and given that it is currently being considered by Parliament and is not yet
law, the Commission notes there will be the ability to conditionally exclude certain
routes from the standard access obligations in an access determination (assuming the
proposed legislation passes in its present form).52 The Commission also considers
that Telstra’s proposed automatic exclusion may cause uncertainty for industry and
that further consultation would be required.53
3.2 Draft final report
The Commission received submissions on the revised service description which, for
the most part, supported the approach taken by the Commission in the Draft final
report. There were a number which identified further changes or areas requiring
clarification including the need for the DTCS service description to:
� either delete or define the word ‘symmetric’
� specifically identify ‘Ethernet over SDH’ in the service description
� re-define ‘uncontended’ so that it does not exclude ‘Ethernet over fibre’
services
� re-define ‘network interfaces’ to remove ambiguity
� include an automatic exemption clause.
51
The proposed legislation includes the Telecommunications Legislation Amendment (Competition and
Consumer Safeguards) Bill (the CACS Bill) or the Telecommunications Legislation Amendment
(National Broadband Network Measures—Access Arrangements) Bill 2010 (Access Bill). 52
See for example proposed paragraph 152BC(3)(h) inserted by item 116 of the CACS Bill. 53
Refer to sections 152AS to 152ATA of the Act.
18
Delete or define the word ‘symmetric’
VHA submits that the word ‘symmetric’ should be taken out of the opening wording
of the service description on the basis that it is not required54 while Optus submits
that it should be defined as ‘the same data rate in both directions’.55
Identify ‘Ethernet over SDH’ in the service description
Telstra repeats the submission that ‘Ethernet over SDH’ be specifically identified in
the service description on the basis that it would create the greatest level of certainty
over the Ethernet technology which the Commission intends to regulate. Telstra
nevertheless supports the use of the words ‘permanent’, ‘uncontended’ and
‘symmetric’ in the service description in order to identify ‘Ethernet over SDH’ should
the Commission choose not to specifically name ‘Ethernet over SDH’.56
Re-define ‘uncontended’ so that it does not exclude ‘Ethernet over fibre’ services
Optus submits that by defining ‘uncontended’ as ‘dedicated and not shared’ the
proposed definition has the potential to exclude ‘Ethernet over fibre’, or native
Ethernet services, which can be considered as both shared and uncontended. In doing
so the proposed definition would go against the objective of having a declaration
which is technologically neutral in circumstances where transmission technology is
moving towards Ethernet over fibre. It would also impede access seeker ability to
access DTCS services which use Ethernet network interfaces. Optus proposes the
following alternative definition in order to overcome such an eventuality:
Uncontended means that the sum of the total bandwidth assigned to users on a
given transmission link is no more than the total bandwidth available, ie. the
bandwidth assigned to each user is guaranteed.57
Re-define ‘network interfaces’ to remove ambiguity
A number of submissions were made in relation to the definition of ‘network
interfaces’. Austar suggests that it be amended to mean ‘a network interface,
including Ethernet’.58
VHA submits that the following words be added (italicised)
‘include, but are not limited to Ethernet, PDH an SDH network interfaces…’ to
ensure that new network interfaces are accommodated.59

Telstra argues that the DTCS should not cover Ethernet network interfaces but that if
the Commission is minded to include Ethernet network interfaces as well as PDH and
SDH network interfaces, it should define ‘network interfaces’ to include only these
three. To this end the definition should be exhaustive so that it does not capture
services going into data centres with different network interfaces and network
interfaces yet to be developed without any analysis of markets they serve or state of
competition. For the definition to be exhaustive the word ‘including’ should be
changed for ‘are’.
Telstra also submits that the proposed variation is too broad and would lead to
regulation of Ethernet services supplied by access seekers using their own
infrastructure or using ULLS and SDH inputs.60
Include an automatic exemption clause
Telstra’s submissions concerning the automatic clause are similar to the submissions
it made on the Discussion paper.61
The Commission’s view
The Commission considers that the service description proposed in the Draft final
report (set out in Appendix 2 and adopted in this Final report) adequately balances the
need to define the DTCS so that it extends to wholesale transmission services but is
broad enough that it captures all point to point transmission services irrespective of
the network interface or underlying input used to provide each service.
The Commission considers it necessary to describe network interfaces as ‘symmetric’
in order to avoid capturing services such as DSL. The Commission notes that
‘symmetric’ is a term which is widely understood by the telecommunications industry
to mean the same data in both directions and that it does not therefore require
defining within the DTCS service description. The Commission also does not
consider it necessary to specifically refer to Ethernet over SDH in the DTCS service
description as it is already adequately covered in the revised service description with
‘…symmetric network interfaces on a permanent, uncontended basis’.
In relation to Optus’ submission on the definition of ‘uncontended’, the Commission
notes that Telstra retains control of the quality of its business grade services (such as
the ‘Ethernet over fibre’ services) whereas the DTCS is a transmission service in
which the supply and quality of service is controlled by the access seeker. The
Commission does not intend to regulate business services such as Telstra’s ‘Ethernet
over fibre’ and is not persuaded by the proposition that the revised service description
is not in the LTIE or in accordance with the principle of regulating the underlying
transmission service irrespective of the interface used to deliver the service.
60
Telstra submission on the Draft final report, p.17. 61
Telstra submission on the Draft final report, pp.24-25.
20
Finally, the Commission notes that the definition of ‘network interfaces’ is intended
to be inclusive so that the service description captures transmission services
irrespective of the network interface used to provide the service. The Commission
considers that the revised definition achieves this objective. The Commission also
considers that declaration and exemption inquiries already provide for regular
assessment of the state of competition in DTCS markets and that it is not necessary
therefore to conduct a market analysis every time the industry adopts a new network
interface.
21
4 Will varying the declaration promote competition?
4.1 The Commission’s approach to defining markets
Defining markets relevant for transmission services allows the Commission to
meaningfully analyse the effectiveness of competition, and the likely effect of varying
the existing DTCS declaration. The markets identified may be for declared
transmission, non-declared transmission, or any relevant downstream markets.
The Act directs the Commission’s attention to the markets for listed services in which
competition may be promoted. In most cases, this is likely to be the markets for
downstream services rather than the market in which the eligible service is supplied.
The process of market definition also involves determining the market boundaries of
transmission or any downstream markets, which can be described in product,
geographic and functional terms.62
4.2 Defining the market in which the eligible services are supplied
In the 2009 DTCS Final report, the Commission identified the relevant downstream
markets for the DTCS as the range of retail services (that can be supplied using
transmission services) which are delivered over optical fibre including national long distance, international call, data and IP-related markets. The Commission also found
that mobile services including voice and data were relevant downstream markets.
The Commission sought submissions in the Discussion paper on whether the
proposed variation to the service description of the DTCS declaration was likely to
have an impact on the definition of markets for transmission services.
Market definition
Telstra submitted in its submissions on the Discussion paper that the proposed
variation would extend the market definition for transmission services well beyond
what is normally considered a ‘transmission service’. Telstra argued that the market
relating to the proposed service description in the Discussion paper could include
Ethernet services at multiple network layers and that the proposed variation is
inconsistent with the method of market definition normally adopted by the
Commission. Telstra considered that the Commission should undertake analysis of
the different wholesale markets and also undertake a proper analysis of product
substitutability in Ethernet markets. Telstra’s key argument was that declarations
should not simultaneously apply to multiple product markets and regulate products
that are inherently not substitutable given that they exist in different markets. Telstra
62
ACCC, Merger Guidelines, November 2008, p. 15. ACCC, Telecommunications services –
Declaration provisions – a guide to the declaration provisions of Part XIC of the Trade Practices
Act, July 1999, pp.40-47.
22
was also concerned that under the proposed variation in the Discussion paper,
asymmetric services such as DSL might be captured within the same markets as
Ethernet.63
Telstra argued that the position adopted by the Commission is inconsistent with
international approaches to the regulation of Ethernet. Although regulation of
Ethernet has been considered necessary in some overseas jurisdictions, in the UK,
SDH/PDH transmission was found to exist in a different wholesale market to
Ethernet-based transmission, and regulation of Ethernet only applied to Ethernet
services utilising low bandwidth and terminating services. In Canada, Ethernet-based
transmission services are also defined and regulated separately to traditional SDH and
PDH transmission.64
VHA and Macquarie Telecom submitted that they did not expect the proposed
variation in the Discussion paper to have any effect on the market definition for
transmission services.65
Macquarie Telecom reasoned that while Ethernet network
interfaces, in addition to other existing protocols, might change the style of delivering
services to end-users it would not change the services delivered to end-users per se on
the basis that no new services would be created nor would any existing services be
withdrawn as a result of the proposed variation.66
Geographic dimension
In establishing the geographic dimensions of the market, the Commission has regard
to factors including any limitations on the ability of access to alternative sources of
supply in different regions; the costs of switching to alternative sources of supply;
and the relative price levels and price movements of different geographic sources of
supply.67
The 2009 DTCS Final report found that broad geographical categories for
transmission services were useful in identifying particular transmission markets. The
Commission concluded that the geographic markets encompassed inter-capital
transmission, capital-regional routes, inter-regional routes and local exchange and
tail-end transmission in regional, metropolitan and CBD areas.68
In the Discussion paper, the Commission sought views on whether the geographic
dimension of the transmission services markets was likely to be affected by the
proposed variation to the DTCS service description.
Telstra submitted that the geographic scope for regulation would be greatly increased
due to the broader functional scope of the service description and the different
geographical areas supplied by that broader functional scope. Telstra argued that,
currently, there is no geographical impediment in Ethernet markets and that the

ACCC, 2009 DTCS Final report, p.10.
23
Commission should define the service description to automatically exclude any routes
where there are multiple competitors with excess capacity.69
In response to the Draft final report, Telstra submits that it fails to adequately address
the geographic aspect of the declaration and that the declaration will potentially apply
to locations where there is already effective competition. Telstra argues that the Final
Exemption Decision is based on information collected in 2007 and that since then
competition has increased due to new investment, an introduction of Government
funded competitors and advances in alternative transmission technologies. Telstra
also considers that the geographic footprint of competition for Ethernet services is
different to that of SDH transmission and that long term leases should also be
considered equivalent to fibre build for exemption purposes. Telstra considers that
there are a significant number of routes subject to regulation which have two or more
fibre infrastructure competitors and that it is incumbent on the Commission to
consider the impact of the geographic reach of competition and update the scope of
declaration accordingly.70
In their submissions on the Discussion paper, VHA and Macquarie Telecom
submitted that they did not consider that the proposed variation would impact the
geographic dimensions for the declared DTCS.71 Macquarie Telecom reasoned that
this was because Ethernet network interfaces (in addition to other existing protocols)
applied equally across the geographic markets and that no new geographic markets
would be created nor would any existing geographic markets be closed as a result of
the proposed variation.72
Technologies used to provide transmission services
In the 2009 DTCS Final report and Final Exemption Decision, the Commission
concluded that optical fibre remained the dominant technology for the provision of
transmission services despite the alternate technologies which are sometimes utilised
for a similar function.73
The Commission sought submissions in the Discussion paper on whether the
proposed variation to the DTCS service description to include Ethernet network
interfaces would have an impact on the use of optical fibre for the provision of
transmission services.
Telstra submitted that the proposed regulation would adversely influence technology
choice and impede its adoption. Telstra also argued that the proposed regulation of

ACCC, 2009 DTCS Final report, pp.14-15.
24
Ethernet would impede the long-term development of effective infrastructure
competition.74
VHA submitted that SDH, PDH and Ethernet are the technologies which are almost
universally used to deliver the DTCS by optical fibre and that the proposed variation
to the service description to include Ethernet network interfaces would not affect the
use of optical fibre for the provision of transmission services.75
Macquarie Telecom
agreed that the proposed variation would have no impact on the use of optical fibre
because the use of Ethernet network interfaces equally applied to optical fibre as the
existing network interfaces and no new technology would be required for the use the
Ethernet network interfaces.76
The Commission’s view
The Commission is of the view that the proposed variation to the DTCS service
description is unlikely to alter the definition of downstream DTCS markets identified
by the Commission in 2009 DTCS Final report. The inclusion of Ethernet network
interfaces in the DTCS service description is not expected to, by itself, create new
services and geographic markets, withdraw services or close markets.
The Commission notes that Ethernet network interfaces use optical fibre as do SDH
and PDH network interfaces and that the variation to the DTCS service description
will not therefore affect the use of technology in the provision of transmission
services or create new data delivery methods.
Furthermore, the Commission notes its findings in the 2009 DTCS Final report that
alternative technologies which may be employed for certain aspects of transmission
do not possess the full range of service attributes as optical fibre. For example, the
Commission does not consider microwave services will become a viable substitute on
capital-regional routes given that it cannot be utilised effectively across the entire
range of downstream demands.
Similarly, tail-end transmission technologies such as Unconditioned Local Loop
Service (ULLS), Hybrid Fibre Coaxial network (HFC), Local Multipoint Distribution
System (LMDS) and Multi-Channel Multipoint Distribution System (MMDS) are
unable to match optical fibre in terms of capacity or customer acceptance for the full
range of transmission requirements.77
The Commission is therefore of the view that the variation of the service description
to include Ethernet network interfaces will not alter the viability of such technologies.

ACCC, 2009 DTCS Final report, pp.14-15.
25
The Commission considers that the revised service description in the Draft final
report addresses Telstra’s concern over possible regulation of multiple network layers
or asymmetric services such as DSL where it describes network interfaces as
‘symmetric’ and delivered on an ‘uncontended’ and ‘permanent’ basis. The
Commission further notes that Telstra has not made any further submissions on this
point in its submissions on the Draft final report.
In relation to the suggestion that government funded competitors provide competitive
constraints, the Commission notes that most of these services are either in their
infancy or still in the process of being rolled-out. Further, any long-term leased
transmission services in declared areas are provided on the existing underlying
infrastructure which is the source of the bottleneck for the DTCS.
Finally, the Commission considers that the routes which were exempted in the 2009
Final Exemption Decision adequately address Telstra’s concerns over regulation of
transmission markets with effective competition or contestability. As already stated
earlier in this Final report, the Commission considers that deregulation should be
achieved through the existing exemption process and not using conditional
mechanisms in a declaration.
4.3 Market Structure
Market structure is an important determinant of a competitive market. When
examining the effect of the proposed variation on the structure of transmission
markets the Commission is interested in assessing whether the current number of
participants in transmission services is likely to change via new market entry or
existing players exiting the market.
In the 2009 DTCS Final report, the Commission found that existing capital-regional
or inter-capital fibre networks which were less than 1 km from a town’s regional post
office could provide a constraint on incumbent behaviour and pricing. Nevertheless,
there was limited contestability in metropolitan and CBD tail-end transmission
markets and relevant markets for many inter-exchange transmission services. The
Commission considered high sunk costs in the transmission market represented a
significant barrier to entry making it economically inefficient to duplicate existing
network infrastructure. The Commission also found that optical fibre was likely to
remain the dominant technology across all transmission services, and that high
barriers to entry in many DTCS markets were likely to remain.78
In the Discussion paper, the Commission sought comments on whether the market
structure for the DTCS was likely to be affected by the proposed variation to the
DTCS service description.
78
ACCC, 2009 DTCS Final report, p.20.
26
Telstra submitted that the proposed variation of the service description in the
Discussion paper risked catching a wide range of new wholesale and retail markets,
that it might have an adverse impact on competition in downstream markets on the
basis that it would impede upstream infrastructure investment and slow facilities
based competition in wholesale markets. Additionally, Telstra argued that the
declaration itself becomes a barrier to entry in transmission markets by deterring
potential infrastructure-based competitors. As a result, Telstra submitted that the
proposed variation could lead to regulation of a range of services at multiple layers of
the supply chain.79
Macquarie Telecom reasoned that while the use of the Ethernet network interfaces (in
addition to other existing protocols) would affect the style of delivering services to
end-users, it would not materially alter the height of entry barriers per se as they
applied to transmission markets. The outcome of the proposed variation would
therefore be to create the potential for variation to the style of service delivery. There
would be no change to the optical fibre delivery platform, or any material change in
the cost structure of end-user service delivery as a result. As such, Macquarie
Telecom did not expect the proposed variation to change existing incentives for
potential entrants to the market for transmission services.80
Macquarie Telecom predicted that the proposed variation would have a positive (and
likely minor) effect on competition in downstream markets on the basis that the
proposed variation would ensure that Telstra would supply the DTCS using Ethernet
network interfaces which in turn would create opportunities for retail operators to
offer competitive services to end-users.81
VHA agreed that the proposed variation would not affect the barriers to entry. To the
extent Ethernet network interfaces were not covered by the current service
description, VHA submitted that the proposed variation promoted competition in
downstream markets for the reasons set out by the Commission in the 2009 DTCS
Final report.
To the extent Ethernet network interfaces were covered by the current service
description, VHA submitted that the variation promotes the LTIE as it removes any
doubt regarding the scope of the declaration and provides additional business
certainty for access providers with respect to their investment decisions and for access
seekers with respect to the scope of the declared DTCS.82
The Commission’s view
The Commission considers that the proposed variation to the DTCS declaration
would not alter the Commission’s market analysis or affect the Commission’s

27
findings in the 2009 DTCS Final report. In its March 2009 Final report,83
the
Commission found a range of downstream markets relevant for the purposes of
evaluating whether the DTCS declaration would promote competition. These
downstream markets included national, long distance, international call, data and IP-
related markets, mobile and local call markets.84 In 2009 the Commission also
exempted particular routes from regulation based on the existence of competition and
irrespective of the network interface used.85
The Commission reaffirms its competition analysis in the 2009 DTCS Final report
that the declared DTCS is largely characterised by significant barriers to entry caused
by the cost of laying fibre, limited supply or demand side substitutability and a
dominant incumbent.86
The competition analysis in the 2009 DTCS Final report did
not define network interface specific markets, rather it assessed the DTCS market as a
whole. For this reason, the Commission does not consider that the downstream
markets for the DTCS and the state of competition are likely to have changed.
The Commission also does not consider it necessary to separately define DTCS
markets on the basis of network interfaces used to provide the service or conduct
definitive competition analysis on this basis. The Commission notes that it is
sufficient under Part XIC of the Act to broadly identify the scope of relevant markets
likely to be affected by the declaration and that a market definition analysis should be
seen in the context of shedding light on how a variation would promote competition
rather than in the context of developing ‘all purpose’ market definitions.87
Further, the inclusion of Ethernet network interfaces in the DTCS service description
will not affect the use of optical fibre as the main technology for the delivery of the
DTCS nor the high sunk costs which are associated with laying it.
The Commission considers that, irrespective of the cost of technology used to convert
to an Ethernet interface protocol, a bottleneck exists in DTCS routes which are
currently declared. This bottleneck affects the state of competition in DTCS markets
and exists irrespective of the network interface used to deliver the service. Where it
does not, the Commission has exempted the route from regulation. The state of
competition in DTCS markets does not therefore pivot on a particular network
interface but on other factors which prevent entry into the market such as the high
cost associated with laying optic fibre, the absence of substitute services and presence
of a dominant incumbent. It is for this reason that the Commission does not consider
further market analysis on transmission services delivered via a particular network
interface to be necessary to assessing the current and likely future state of
competition, with or without the variation to the service description.

4.4 Conclusion on whether the proposed variation will promote
competition
The revised service description in Appendix 2 provides a technology-neutral
approach to the regulation of transmission services. It will promote competition by
ensuring that access seekers continue to be provided with the DTCS, where the
market would otherwise not be competitive, without being limited by the network
interface used to provide the service. Without the variation to the DTCS declaration,
the state of competition in markets of transmission services using Ethernet network
interfaces is likely to remain the same where they are uncompetitive due to the cost of
laying fibre, limited substitutability and a dominant incumbent.
The Commission notes that the DTCS requires network interfaces in order to operate
and that by ensuring that the DTCS service description covers Ethernet network
interfaces, the variation removes obstacles of access to transmission services which
use this particular network interface as its underlying technology.
In addition to gaining access to DTCS services which use Ethernet network
interfaces, the Commission is cognisant of how critical it is for access to be at a
reasonable price in order to ensure continued innovation and vigorous competition in
downstream services. The Commission is of the view that by varying the service
description to include Ethernet network interfaces, innovation and competition in
downstream services will be further encouraged as transmission services delivered via
Ethernet network interfaces create opportunities for retail operators to offer
competitive services to end-users.
The Commission will remain attentive to developments in the market and assess any
potentially competitive services with a view of rolling back regulation where it is
found to be in the LTIE.

5 Will varying the declaration achieve any-to-any
connectivity?
In determining whether the DTCS declaration should be varied the Commission must
make an assessment as to whether a variation to the service declaration would be
likely to achieve any-to-any connectivity in relation to carriage services that involve
communication between end-users. In the 2009 DTCS Final report, the Commission
found that the variation to the declaration would not have an impact on the
achievement of any-to-any connectivity between end-users.
In the Discussion paper, the Commission sought views on whether the proposed
variation to the DTCS service description to include reference to network interfaces
and a minimum data rate is likely to affect the achievement of any-to-any
connectivity between end-users.
Telstra submitted that the proposed variation was unlikely to affect any-to-any
connectivity given that there is no evidence of Ethernet being unavailable in the
market or any refusal of providers to supply it.88
Macquarie Telecom submitted that
the proposed variation would not impinge on any-to-any connectivity as Ethernet
network interfaces (in addition to other existing protocols) might change the style of
delivering services to end-users but not the ability of any end-user to connect with
another end-user.89
VHA did not expect there to be any impact on any-to-any
connectivity.90
The Commission’s view
The Commission notes the submissions from Macquarie Telecom and Optus which
suggest that there have been instances where Telstra has refused to supply wholesale
transmission services using Ethernet network interfaces in the past.91
The
Commission also notes Telstra’s submission that it occasionally has been unable to
meet access seeker requests in particular areas where the local exchange locations
were not enabled for the supply of Ethernet services but that it is unaware of any
instance of refusal to supply Ethernet services in areas enabled for the provision of
such services.92
Although the Commission does not consider that it is at present in a position to
determine whether Telstra has refused to supply transmission services using Ethernet
network interfaces, the Commission nevertheless considers that the proposed
variation to the DTCS service description will serve to encourage any-to-any
connectivity between end-users in relation to voice and data services which use

transmission services delivered via Ethernet network interfaces. The Commission
considers that this is likely given the prevalence of current use of Ethernet in
telecommunication equipment and delivery of services in the telecommunications
market.
31
6 Will varying the declaration encourage efficient use of,
and investment in, infrastructure?
In assessing whether a variation to the DTCS service description will promote the
LTIE the Commission must consider whether it is likely to encourage the
economically efficient use of, and economically efficient investment in:
� infrastructure by which listed services are supplied, and
� any other infrastructure by which listed services are, or are likely to become,
capable of being supplied.
The Commission considers that efficiency has three major components – allocative,
productive and dynamic. In general, each of these forms of efficiency is enhanced
when prices of given services reflect the underlying costs of providing these services.
These components are discussed further in Appendix 3.
In its 2009 DTCS Final report, the Commission was of the view that the varied 2009
DTCS declaration promoted both the efficient use of and efficient investment in
infrastructure.
In the Discussion paper, the Commission sought submissions on whether the
proposed variation to the DTCS service description to include reference to network
interfaces and a minimum data rate would encourage or discourage the efficient use
of, and investment in, infrastructure.
Telstra submitted that the proposed variation of the DTCS would not encourage
efficient investment as regulating at higher layers offers access seekers a choice
between creating their own service (based on the regulated lower layer inputs) or
simply buying the end product. Telstra submitted that this would result in reliance on
regulated access products and reduce investment in key infrastructure and alternative
infrastructure.93
Telstra also argued that introducing regulation at multiple layers would:
� distort investment decisions and increase the likelihood of inefficient
outcomes
� distort build/buy signals and create scope for significantly regulatory arbitrage
� distort prices across downstream and substitute services, and
� distort and deter new investment and impede the long-term development of
effective infrastructure competition, particular backhaul services.94

Telstra submission on discussion paper, pp. 4 (in Executive Summary), 14, 16, 36. Telstra
submission on Draft final report, p.14
32
Telstra submitted that double regulation of substitute products could lead to
inefficient investment decisions since the risk of error in relative pricing is greatly
increased. Access providers would also be wary as to their ability to recover their
actual costs under an ‘efficient cost’ pricing construct and the move to wholesale
price controls as contemplated by the new legislative regime.95
Further, the proposed variation had the potential to deter and delay investment in, and
the roll out of, new wholesale Ethernet services (because any new technology will be
subject to regulation) and that internationally regulatory forbearance has occurred in
markets where Ethernet is still in the early stages of deployment to encourage
innovation and investment in the technology.96
Regulation would also not promote
efficient use of Ethernet interfaces, or transmission infrastructure, because access
seekers are able to self-supply Ethernet services and there is a widespread commercial
supply by a number of carriers.97
Macquarie Telecom, Optus, VHA and Access seekers found that the proposed
variation would encourage efficient use, and efficient investment in, infrastructure.98
Macquarie Telecom was of the view that the proposed variation ensures that Ethernet
network interfaces are integral to the DTCS and this supported investor confidence in
investments which are dependent on the DTCS. Macquarie Telecom considered
investment in a service or infrastructure which includes Ethernet to be preferable to
an investment which excludes Ethernet.99
Optus considered that the inclusion of Ethernet network interfaces in the service
description was likely to facilitate more widespread adoption of and investment in
modern transmission technologies. The availability of wholesale Ethernet would
enable more advanced services to be provided by a greater number of carriers and
stimulate greater service differentiation and product choice in the market. It would
also enable a greater number of entrants to build a retail customer base and this in
turn would encourage such carriers to invest in their own infrastructure in the
future.100
VHA submitted that the proposed variation to the service definition creates an
incentive (albeit a moderate one) for an access provider to deliver transmission
capacity services through a technology not covered by the declaration. VHA did not
consider at this stage that viable alternatives to the network interfaces proposed by the
Commission existed or that the newly created incentive would be sufficient for an
access provider to change their technology choice. VHA submitted that the risk of the
service description distorting investment decisions would be minimised if it expressly

states that it is intended to be technology neutral and if the Commission determines
that including additional network interfaces is a variation of a minor nature for the
purpose of s.152AO(3) of the Act, thereby forgoing the need for a further public
inquiry.
To the extent Ethernet network interfaces are not covered by the current service
description, VHA submitted that the variation promotes the efficient investment in
infrastructure for the reasons in the 2009 DTCS Final report. To the extent Ethernet
network interfaces are covered by the current service description, VHA expected the
proposed variation would moderately encourage economically efficient use of, and
investment in, transmission infrastructure (over and above declaration itself). As
submitted above, the clarification of the service definition provides additional
business certainty for access providers with respect to their investment decisions and
for access seekers with respect to the scope of the declared DTCS. VHA strongly
supported the Commission’s move to improve business certainty with respect to
declared services.101
The Access seeker submission submitted that Ethernet layer services (as opposed to
IP layer) are essential for connecting their IP DSLAMs back to their core networks.
The lack of clarity about the application of the current DTCS declaration to Ethernet
interface and transport detracted from the access seekers’ ability to deploy DSLAMs
at exchanges where only Telstra transmission is available.
Furthermore, an inability to obtain reasonably priced access to Ethernet backhaul has
led to access seekers having to purchase 34 Mbit/s backhaul and then move to STM-
1 (155 Mbit/s) backhaul links depending on the level of traffic per access seeker
DSLAM site. Access seekers regarded this as inefficient (and not in the LTIE) when
Ethernet capacity increments can be less than 1 Mbit/s thereby avoiding unnecessary
wastage of network capacity by access seekers.102
The Commission’s view
The Commission notes that the purpose of the variation inquiry is to remove any
ambiguity about the services covered by the DTCS and to ensure that the service
description has the effect of being appropriately technologically neutral by including
reference to all commonly used network interfaces in a way which is able to adapt to
new network interfaces as they emerge.
The Commission has had regard to the submissions on the cost effectiveness and
efficiencies of Ethernet technologies. The Commission does not consider that it is in
the LTIE to limit the network interface in the DTCS service description based on
whether access seekers can access Ethernet over SDH. The Commission also
considers that it would be inefficient to require access seekers to convert a
transmission service using an SDH network interface to an Ethernet network interface
101
VHA submission on discussion paper, p.10. 102
Access seeker submission on discussion paper, p.3.
34
as it would require the provision of additional electronic equipment by access seekers
when access providers can supply the same service by inserting an Ethernet line card
into an SDH multiplexer in areas where it is technically possible. The Commission
further notes that there are cost related and technical efficiencies which can be gained
from using Ethernet network interfaces in the delivery of transmission services to
end-users and that these will serve to encourage efficient use of the infrastructure
used to deliver the DTCS.
The Commission considers that it is technically feasible for access providers to
provide the DTCS using Ethernet network interfaces given the prevalence of Ethernet
network interfaces in the current transmission market and the fact that it is likely to be
used in future upgrades to Australian telecommunication networks.
The Commission considers that it has addressed Telstra’s concerns over regulation of
higher or multiple layers in the revised service description and notes that it did not
receive any submissions from access providers on whether the cost of supply of the
DTCS using Ethernet network interfaces were unreasonable or whether the supply of
the DTCS using Ethernet network interfaces would have particular effects on the
operation or performance of telecommunications networks. The Commission is of the
view that these are not issues for access providers whilst noting access seeker
submissions which describe Ethernet interfaces as the preferred interface for
providing cost effective and scalable interfaces.103
The Commission considers that the technical feasibility by which access seekers are
able to obtain transmission services and provide retail services to end-users is
increased by the revised service description as it incorporates Ethernet network
interfaces, the default standard for vendors of telecommunication equipment and
preferred network interface for broadband networks. The Commission also has regard
to the legitimate commercial interests of access providers, including their ability to
exploit economies of scale and scope, and considers that these interests will be
enhanced by the revised service description as it serves to clarify the services covered
by the DTCS declaration.
The Commission notes access seeker views which, in different ways, submit that the
proposed declaration variation will encourage efficient use, and investment in,
infrastructure used to supply the DTCS, or at the very least not discourage it. The
Commission considers that DTCS routes which have been recently exempted from
the DTCS declaration as evidence that regulation has helped to encourage efficient
investment in infrastructure used to provide the DTCS.
The Commission notes that the revised service description will also serve to cover
transmission services where there is a lack of effective competition irrespective of
network interface. This will provide certainty for CSPs’ investment decisions and is
likely to encourage efficient investment by CSPs once they secure a retail customer
base of a certain threshold.
103

7 The Commission’s overall conclusion
The Commission considers that the variation to the DTCS service description is in the
LTIE as it serves to ensure that regulation of the DTCS encourages competition in
relevant DTCS markets, promotes any-to-any connectivity between end-users and
encourages efficient use, and investment in, infrastructure used to provide the DTCS
(and related downstream markets) irrespective of network interface used.
The Commission considers that the proposed variation to the DTCS declaration will
promote competition in DTCS markets by ensuring that access seekers will continue
to be provided with the DTCS where the market would otherwise not be competitive.
In doing so the proposed variation will ensure regulation of the DTCS where there is
a lack of competition in DTCS markets and not on whether it is delivered via a
particular network interface.
The Commission considers that the proposed variation will encourage any-to-any
connectivity between end-users given the prevalence of the current use of Ethernet in
telecommunication equipment and delivery of services in the telecommunications
market.
The Commission considers that efficient use of infrastructure used to provide the
DTCS will be promoted by the proposed variation. The Ethernet network interface is
common in modern network equipment and likely to be used in future upgrades to
Australian telecommunication networks. The Commission notes that adapters or other
equipment are unlikely to be necessary where Ethernet network interfaces are used
given the prevalence of Ethernet in the market. The Commission considers that the
use of Ethernet network interfaces is likely therefore to be more cost effective than
other network interfaces. The Commission is also of the view that the variation to the
declaration will provide certainty for CSPs in their investment decisions and help
them build a customer base as a consequence. The Commission considers that this
will encourage them to invest in efficient infrastructure once their retail customer
base reaches a certain threshold

8 Other issues
8.1 National broadband network products and the DTCS
A number of submissions considered the likely impact of the DTCS declaration
variation on NBN services. AAPT submitted that the DTCS declaration remain
unchanged until the industry has more clarity on NBN services and the Commission
has conducted a full inquiry into how these services should be declared.
Telstra submitted that any regulation of emerging national broadband network (NBN)
services was premature in circumstances where the future industry structure is still the
subject of ongoing analysis and negotiation. Telstra also submitted that regulation
should not apply to any transmission routes where an NBN corporation has overbuilt
existing transmission of any carrier.104
VHA considered that it was too early to assess how NBN Co’s (potential)
transmission services would impact various markets for the declared DTCS.105
The Commission’s view
The Commission agrees that there is uncertainty surrounding the services which NBN
corporations will be providing and how they will be regulated. The Commission also
considers that it is too early to assess the impact of the NBN on DTCS markets.
The Commission nevertheless considers that until details of NBN final service
offerings are finalised, regulation of the DTCS is in the LTIE regardless of whether it
is supplied over Ethernet, PDH or SDH network interfaces and regardless of the
access provider supplying it. Services provided by NBN corporations which fall
within the scope of the DTCS declaration will either be regulated under the current
access regime or be regulated under an NBN corporation specific access regime if the
Telecommunications Legislation Amendment (Competition and Consumer
Safeguards) Bill (the CACS Bill) and/or the Telecommunications Legislation
Amendment (National Broadband Network Measures—Access Arrangements) Bill
2010 (Access Bill)106
are passed into law.
In relation to whether NBN services will provide competitive or substitute services in
transmission markets, the Commission notes that it has an ongoing commitment to
assessing the level of competitiveness in DTCS related markets, including the effect
of NBN services when these are made available, with a view of rolling back
regulation where it is found to be in the LTIE.

8.2 Quality of service
AAPT submitted that there may be risks in varying the declaration without any
reference to quality of service or security aspects of the services when regard is had to

The Commission notes that the DTCS is a transmission service in which the access
seeker controls the quality of service which it provides to end-users.

Appendix 3 - Long-term interests of end-users
Section 152AB of the Act states that, in determining whether declaration promotes
the LTIE, regard must be had to the extent to which declaration is likely to result in
the achievement of the following objectives only:
� promoting competition in markets for listed services
� achieving any-to-any connectivity in relation to carriage services that involve
communication between end-users, and
� encouraging the economically efficient use of, and the economically
efficient investment in: (i) the infrastructure by which listed services are
supplied; and (ii) any other infrastructure by which listed services are, or are
likely to become, capable of being supplied.
These objectives are interrelated. In many cases, the LTIE may be promoted through
the achievement of two or all three of these matters simultaneously. In other cases,
the achievement of one of these matters may involve some trade-off in terms of
another of the matters, and the Commission will need to weigh up the different effects
to determine whether remaking, extending, revoking or varying the existing
declaration, or allowing it to expire promotes the LTIE. In this regard, the
Commission will interpret ‘long-term’ to mean a balancing of the flow of costs and
benefits to end-users over time in relation to the criteria. Thus, it may be in the LTIE
to receive a benefit for even a short period of time if its effect is not outweighed by
any longer term cost.
The following discussion provides an overview of what the Commission must
consider in assessing each of these objectives.
Promotion of competition
Subsections 152AB(4) and (5) of the Act provide that, in interpreting this objective,
regard must be had to, but is not limited to, the extent to which the arrangements will
remove obstacles to end-users gaining access to listed services. The explanatory
memorandum to Part XIC of the Act states that:
...it is intended that particular regard be had to the extent to which the...
[declaration]... would enable end-users to gain access to an increased range or
choice of services. 108
The concept of competition is of fundamental importance to the Act and has been
discussed many times in connection with the operation of Parts IIIA, IV, XIB and

Trade Practices Amendment (Telecommunications) Act 1997 (Cth) explanatory memorandum.

In general terms, competition is the process of rivalry between firms, where each
market participant is constrained in its price and output decisions by the activity of
other market participants. The Trade Practices Tribunal (now the Australian
Competition Tribunal) stated that:
In our view effective competition requires both that prices should be flexible,
reflecting the forces of demand and supply, and that there should be independent
rivalry in all dimensions of the price-product-service packages offered to
consumers and customers. Competition is a process rather than a situation.
Nevertheless, whether firms compete is very much a matter of the structure of the
markets in which they operate. 109
Competition can provide benefits to end-users including lower prices, better quality
and a better range of services over time. Competition may be inhibited where the
structure of the market gives rise to market power. Market power is the ability of a
firm or firms to constrain or manipulate the supply of products from the levels and
quality that would be observed in a competitive market for a significant period of
time.
The establishment of a right for third parties to negotiate access to certain services on
reasonable terms and conditions can operate to constrain the use of market power that
could be derived from the control of these services. Accordingly, an access regime
such as Part IIIA or Part XIC addresses the structure of a market, to limit or reduce
the sources of market power and consequent anti-competitive conduct, rather than
directly regulating conduct which may flow from its use, which is the role of Part IV
and Part XIB of the Act. Nonetheless, in any given challenge to competition, both
Parts XIB (or IV) and XIC may be necessary to address anti-competitive behaviour.
To assist in determining the impact on markets of remaking, extending, revoking or
varying the existing declaration or allowing its expiration, the Commission will first
need to identify the relevant market(s) and then to assess the likely effect on
competition in each market.
Section 4E of the Act provides that the term ‘market’ includes a market for the goods
or services under consideration as well as any other goods or services that are
substitutable for, or otherwise competitive with, those goods or services. The
Commission’s approach to market definition is discussed in its 2008 Merger
Guidelines, is canvassed in its information paper, Anti-competitive conduct in
telecommunications markets, August 1999 and is also explored in the Commission’s
second Fixed Services Review position paper, April 2007.
The second step is to assess the likely effect of the proposal on competition in each
relevant market. As noted above, subsection 152AB(4) requires that regard must be

had to the extent to which a particular thing will remove obstacles to end-users
gaining access to listed services.
The Commission considers that denial to service providers of access to necessary
upstream services on reasonable terms is a significant obstacle to end-users gaining
access to services. In this regard, declaration can remove such obstacles by
facilitating entry by service providers, thereby providing end-users with additional
services from which to choose. For example, access to a mobile termination service
may enable more service providers to provide fixed to mobile calls to end-users. This
gives end-users more choice of service providers.
Where existing market conditions already provide for the competitive supply of
services, the access regime should not impose regulated access. This recognises the
costs of providing access, such as administration and compliance, as well as potential
disincentives to investment. Regulation will only be desirable where it leads to
benefits in terms of lower prices, better services or improved service quality for end-
users that outweigh any costs of regulation.
In the context of considering whether remaking, extending, revoking or varying the
declaration or allowing its expiration will promote competition, it is appropriate to
examine the impact of the existing declaration on each relevant market, the likely
effect of altered access obligations (due to the removal of the declaration) on the
relevant market, and compare the likely competitive environment in that market
before and after the proposed remaking, extension, revocation, variation, or expiration
of the declaration. In examining the market structure, the Commission considers that
competition is promoted when market structures are altered such that the exercise of
market power becomes more difficult; for example, because barriers to entry have
been lowered (permitting more efficient competitors to enter a market and thereby
constraining the pricing behaviour of the incumbents) or because the ability of firms
to raise rivals’ costs is restricted.
Any-to-any connectivity
Subsection 152AB(8) of the Act provides that the objective of any-to-any
connectivity is achieved if, and only if, each end-user who is supplied with a carriage
service that involves communication between end-users is able to communicate, by
means of that service, or a similar service, with other end-users whether or not they
are connected to the same network. The reference to ‘similar’ services in the Act
enables this objective to apply to services with analogous but not identical functional
characteristics, such as fixed and mobile voice telephony services or Internet services
which may have differing characteristics.
The any-to-any connectivity requirement is particularly relevant when considering
services that involve communications between end-users. When considering other
types of services (such as carriage services that are inputs to an end-to-end service or
48
distribution services such as the carriage of pay television), the Commission generally
considers that this matter will be given less weight compared to the other two matters.
Efficient use of, and investment in, infrastructure
Subsections 152AB(6) and (7A) of the Act provide that, in interpreting this objective,
regard must be had to, but is not limited to, the following:
� whether it is, or is likely to become, technically feasible for the services to be
supplied and charged for, having regard to:
� the technology that is in use, available or likely to become available
� whether the costs that would be involved in supplying, and charging
for, the services are reasonable, or likely to become reasonable
� the effects, or likely effects, that supplying, and charging for, the
services would have on the operation or performance of
telecommunications networks
� the legitimate commercial interests of the supplier or suppliers of the services,
including the ability of the supplier or suppliers to exploit economies of scale
and scope, and
� the incentives for investment in:
� infrastructure by which the services are supplied, and
� any other infrastructure by which the services are, or are likely to
become, capable of being supplied.
In considering incentives for investment in infrastructure, the Commission must have
regard to the risks involved in making the investment.
Economic efficiency has three components.
� Productive efficiency refers to the efficient use of resources within each firm
such that all goods and services are produced using the least cost combination
of inputs.
� Allocative efficiency refers to the efficient allocation of resources across the
economy such that the goods and services that are produced in the economy
are the ones most valued by consumers. It also refers to the distribution of
production costs amongst firms within an industry to minimise industry-wide
costs.
� Dynamic efficiency refers to the efficient deployment of resources between
present and future uses such that the welfare of society is maximised over
time. Dynamic efficiency incorporates efficiencies flowing from innovation
leading to the development of new services, or improvements in production
techniques.
49
The Commission will need to ensure that the access regime does not discourage
investment in networks or network elements where such investment is efficient. The
access regime also plays an important role in ensuring that existing infrastructure is
used efficiently where it is inefficient to duplicate investment in existing networks or
network elements.
The technical feasibility of supplying and charging for particular services
This incorporates a number of elements, including the technology that is in use or
available, the costs of supplying, and charging for, the services and the effects on the
operation of telecommunications networks.
In many cases, the technical feasibility of supplying and charging for particular
services given the current state of technology may be clear, particularly where (as in
the present case) the service is already declared and there is a history of providing
access. The question may be more difficult where there is no prior access, or where
conditions have changed. Experience in other jurisdictions, taking account of relevant
differences in technology or network configuration, will be helpful. Generally the
Commission will look to an access provider to demonstrate that supply is not
technically feasible.
The legitimate commercial interests of the supplier, including the ability of the
supplier to exploit economies of scale and scope
A supplier’s legitimate commercial interests encompass its obligations to the owners
of the firm, including the need to recover the cost of providing services and to earn a
normal commercial return on the investment in infrastructure. The Commission
considers that allowing for a normal commercial return on investment will provide an
appropriate incentive for the access provider to maintain, improve and invest in the
efficient provision of the service.
A significant issue relates to whether or not capacity should be made available to an
access seeker. Where there is spare capacity within the network, not assigned to
current or planned services, allocative efficiency would be promoted by obliging the
owner to release capacity for competitors.
Paragraph 152AB(6)(b) of the Act also requires the Commission to have regard to
whether the access arrangement may affect the owner’s ability to realise economies of
scale or scope. Economies of scale arise from a production process in which the
average (or per unit) cost of production decreases as the firm’s output increases.
Economies of scope arise from a production process in which it is less costly in total
for one firm to produce two (or more) products than it is for two (or more) firms to
each separately produce each of the products.
Potential effects from access on economies of scope are likely to be greater than on
economies of scale. A limit in the capacity available to the owner may constrain the
50
number of services that the owner is able to provide using the infrastructure and thus
prevent the realisation of economies of scope associated with the production of
multiple services. In contrast, economies of scale may simply result from the use of
the capacity of the network and be able to be realised regardless of whether that
capacity is being used by the owner or by other carriers or carriage service providers.
Nonetheless, the Commission will assess the effects on the supplier’s ability to
exploit both economies of scale and scope on a case-by-case basis.
The impact on incentives for investment in infrastructure
Firms should have the incentive to invest efficiently in infrastructure. Various aspects
of efficiency have been discussed already. It is also important to note that while
access regulation may have the potential to diminish incentives for some businesses
to invest in infrastructure, it may also ensure that investment is efficient and reduce
the barriers to entry for other (competing) businesses or the barriers to expansion by
competing businesses.
There is also a need to consider the effects of any expected disincentive to investment
from anticipated increases in competition to determine the overall effect on the LTIE.
The Commission is careful to ensure that services are not declared where there is a
risk that incentives to invest may be dampened, such that there is little subsequent
benefit to end-users from the access arrangements.
